Introduction

Replacing the battery in your Toyota Avalon key fob is a simple task that you can do at home. In this guide, I’ll walk you through the process step-by-step. You will only need a flathead screwdriver and a CR2032 battery.

If you don’t have a CR2032 battery, you can purchase one online. I’ve included a link to buy it on Amazon for just a few dollars.

Tools and Materials Needed

• Flathead screwdriver
• CR2032 battery

Step-by-Step Instructions

Step 1: Locate the Indentation

The first step is to find the indentation on your key fob. It’s located on the bottom right where the key ring attaches. This small slot is designed for easy access.

Step 2: Insert the Screwdriver

Take your flathead screwdriver and insert it into the indentation. Twist the screwdriver gently. This will crack open the device, allowing you to lift the cover easily.

Step 3: Remove the Rubber Component

Once the key fob is open, you’ll see a rubber component with buttons. Carefully remove this component and set it aside. Be cautious not to lose any parts.

Step 4: Extract the Circuit Board

The circuit board is the next component to remove. Hold it on the sides to avoid damaging any circuits. Gently slide the old battery out using your fingers.

Step 5: Insert the New Battery

Now, take your new CR2032 battery. Ensure the positive side, which has the text and information, is facing up. Slide it into the slot carefully.

Step 6: Reassemble the Key Fob

After inserting the new battery, place the circuit board back into the rubber component. Make sure it sits securely and aligns with the button openings.

Step 7: Close the Key Fob

Finally, click the back cover onto the key fob. Check that the buttons are working correctly. Your key fob should now be functioning with the new battery.
